I bought a 600 (0.5mm) recently, as well as a Uni Kuru Toga (0.7mm), with the automatically rotating lead.[0] The Kuru Toga’s point stays sharper than the rotring while I write, and always has the same edge. I wasn’t prepared for how well it’s “engine” works. It sits a bit more comfortably in my hand as well. Aesthetically I still prefer the rOtrings look, feel and weight.
